I had a cardinal that just died this afternoon, he was stuck between some rocks and when i went in to grab it by moving a rock, he floated off into the back of the tank. Do I try to remove him? I have a black bristle star, will that be able to handle it? The cardinal is about 1 inch and by the looks of the dead body, some of my shrimps got to him already. I have no intentions of removing my rocks to obtain him. I also blasted behind the tank with a powerhead and all that did was stir up the tank...now its cloudy as heck.
